Answer:
Option C
Step-by-step explanation:
The standard form of equation of a cirle is:
(x-h)^2+ (y-k)^2=r^2
In the given question as the point is given and the radius of circle is given:
So,
(h,k)=(2,-1)
and
r=3
Here,
h=2
k= -1
Putting the values of h,k and r in standard form
(x-2)^2+ (y-(-1))^2=(3)^2
(x-2)^2+ (y+1)^2=(3)^2
So the equation of circle is:
(x-2)^2+ (y+1)^2=9(3)^2
Option C is the correct answer ..
Answer:
1/12
Step-by-step explanation:
When you flip a coin, there are two possible outcomes. When you roll a die there are six possible outcomes. This means the chances of getting a heads is 1/2 and the chances of rolling a 2 are 1/6. To find the probability that both will occur, multiply the two probabilities: 1/6 * 1/2 = 1/12
Answer:
2/3
Step-by-step explanation:
Slope is rise over run which is 2/3
The options are;

dimensions of the photograph
length - 7 inch
width - 5 inch
dimensions of the photo frame is 2x larger than both width and length
length - 7 + 2x
width - 5 + 2x
the perimeter is sum of all 4 sides
Perimeter = 2(7 + 2x) + 2(5 + 2x)
= 14 + 4x + 10 +4x
= 24 + 8x
correct answer is b
